Storage battery cover

Abstract

A cover for an electric storage battery casing having a slide member that is longitudinally adjustable to permit alignment of fill openings formed in the member over electrolyte inlets. The inlets have individual sealing means that cooperate with the slide member underside to close each inlet during battery use.

We claim: 
     
       1. A storage battery cover having at least three battery cell fill inlets for replenishment of electrolyte comprising: an annular rim about the periphery of each inlet having sealing means about the upper surface thereof;   a slide member having a length less than the length of the battery cover but of sufficient length to overlie said inlets with at least portions of the underside thereof having an engagement surface in sealing contact with each sealing means, said slide member including at least two fill openings therethrough located to overlie at least two inlets when said member is moved from a sealed position a predetermined distance; and,   guide means for maintaining the slide member in alignment over said inlets while allowing the movement thereof along the longitudinal axis of said member.   
     
     
       2. The battery cover of claim 1 wherein said sealing means is resilient and selected from the group consisting of O-ring, gasket and washer. 
     
     
       3. The battery cover of claim 2 wherein said rim includes an annular groove with said sealing means comprising an O-ring secured within said groove. 
     
     
       4. The battery cover of claim 1 wherein said guide means comprises edge support strips secured to said case on opposing sides of the slide member. 
     
     
       5. The battery cover of claim 1 wherein said edge support strips comprise brackets having foot portions. 
     
     
       6. The battery cover of claim 2 wherein said slide member includes vent orifices therethrough located within the area defined by each of said engagement surfaces. 
     
     
       7. The battery of claim 6 wherein said slide member includes vent domes extending from the upperside thereof overlying each of said vent orifices. 
     
     
       8. The battery cover of claim 7 having three fill inlets and wherein said slide member includes three vent domes and two fill openings. 
     
     
       9. The battery cover of claim 1 including a stop member positioned thereon to limit the longitudinal movement of said member. 
     
     
       10. The battery cover of claim 2 wherein said engagement surface is convex.
